A butterfly that became extinct over 40 years ago has been bred in a secret forest location.
The chequered skipper has been brought back to the UK after wildlife charity Butterfly Conservation embarked on a project which involved bringing butterflies caught in Belgium back to England where they were released in a secret site.
Dr. Nigel Bourn, of the charity Butterfly Conservation, said: ''I saw in one tiny butterfly the result of so many peoples' hard work and dedication that has got us to this point.''
Another group of 24 Belgian Chequered Skippers has also been released at the undisclosed Rockingham Forest site this month.
Dr. Dan Hoarse, from Butterfly Conservation, added: ''We are in the second year of three-year project. We'll know if it's a success in the long term when we pick up the butterfly in woodland where we didn't let it go.''
